PerFORM was a forms and database application originally developed by Delrina Technology. The product later became associated with Symantec and Adobe, but it is no longer available as a current commercial application.
An FPK file contains communicator packet data in a compressed database format. It is a data file used by PerFORM rather than a document intended for direct editing.
Open an FPK file with the legacy PerFORM software that created it. Because PerFORM is no longer available, modern operating systems generally have no supported application for opening these files.
If the file is needed, use an existing PerFORM installation in its original compatible environment and make a backup copy before attempting to open it.
If the file can be opened in PerFORM, export or copy the required data using that application's available functions.
